Description
Endress+Hauser TMS31: Bulk Storage Safety
The Endress+Hauser iTHERM TMS31 is a specialized, modular multi-point temperature assembly meticulously designed for critical temperature average detection and profiling within challenging storage environments. Specifically engineered for grain, organic bulk material silos, and oil and fuel storage tanks, this device ensures safe, reliable, and economical product storage operations. Its robust mechanical construction, combined with highly accurate temperature sensors (available as up to 20 thermocouple or RTD sensors), are fitted onto a primary metal rope, allowing for precise linear temperature distribution measurements. This innovative design directly addresses the unique demands of bulk storage, safeguarding valuable commodities and preventing hazardous conditions.
Essential for Safe Oil Storage Tanks
The TMS31 is essential for safe oil storage tanks, providing vital temperature monitoring capabilities that are crucial for preventing issues like product degradation, stratification, and even spontaneous combustion in certain hydrocarbon products. In large oil and fuel storage tanks, temperature variations can lead to significant losses in product volume and quality. The TMS31’s ability to offer a linear temperature profile along its impressive immersion length (up to 60,000 mm) allows operators to detect hotspots, monitor exothermic reactions, and ensure uniform storage conditions, thereby maintaining product integrity and adhering to stringent safety regulations. Its robust design and hazardous area approvals ensure reliable performance even in volatile environments.
Revolutionizing Bulk Material Silo Management
For revolutionizing bulk material silo management, the iTHERM TMS31 offers an unparalleled solution for grain and organic bulk material storage. These materials are highly susceptible to spoilage, insect infestations, and spontaneous combustion due to temperature fluctuations and moisture content. The TMS31’s flexible rope design seamlessly adapts to varying silo conditions—during filling, emptying, or static storage—providing continuous, accurate temperature data. This real-time information empowers operators to implement proactive aeration strategies, prevent costly spoilage, and maintain optimal storage conditions, ensuring the quality and longevity of stored agricultural and organic products. Its intrinsically safe design is particularly vital for preventing explosions in dusty environments.
Benefits: Easy Installation and Durability
The TMS31 offers significant benefits: easy installation and durability, making it a cost-effective and reliable solution for long-term temperature monitoring. Its high degree of customization allows for seamless integration into existing or new storage infrastructures, minimizing downtime and installation complexities. The device’s flexible rope design facilitates quick deployment and adaptation to dynamic process conditions within silos and tanks. Furthermore, the TMS31 is engineered for exceptional mechanical robustness, guaranteeing a long product lifetime and continuous, accurate temperature data even under the demanding conditions of bulk material handling. This combination of ease-of-use and ruggedness ensures a superior return on investment.

Intrinsically Safe for Hazardous Locations
The TMS31 is intrinsically safe for hazardous locations, a non-negotiable feature for installations in combustible atmospheres. With comprehensive Ex-approvals including ATEX, IECEx, UL, FM, and CSA, the device is certified for safe operation in areas where flammable gases, vapors, or dusts may be present. This intrinsic safety design limits the electrical and thermal energy to a level too low to ignite a hazardous atmosphere, providing an indispensable layer of protection for personnel and assets. This crucial safety feature ensures compliance with international standards and significantly reduces the risk of accidents in oil tanks and bulk material silos, which are inherently volatile environments.
Optimized for Linear Temperature Distribution
The TMS31 is optimized for linear temperature distribution, featuring a design where multiple sensors are strategically placed along a flexible metal rope. This allows for a precise and continuous temperature profile throughout the height or depth of a storage vessel. Unlike single-point sensors, which provide limited data, the TMS31 delivers comprehensive thermal mapping, enabling accurate detection of temperature gradients, hot spots, and cold spots. This detailed information is critical for identifying potential issues such as material spoilage in silos or stratification in oil tanks, allowing operators to take corrective actions swiftly and maintain optimal storage conditions, thereby enhancing product quality and reducing waste.
Wide Operating Range and Accuracy
The TMS31 offers a wide operating range and accuracy, ensuring reliable measurements across diverse storage scenarios. It supports both Thermocouple (TC) and Resistance Temperature Detector (RTD) technologies, accommodating a broad spectrum of temperatures: Type K up to 800 °C, Type J up to 520 °C, and various Pt100 configurations up to 600 °C. The sensor delivers high accuracy (e.g., Class 1 for TCs, Class A/AA for RTDs) and boasts rapid response times (t50 = 1s for TC, t50 = 3s for RTD), crucial for timely detection of temperature changes. With a maximum process pressure of 40 bar at 20 °C, the TMS31 is robust enough for typical atmospheric and low-pressure storage applications.
